Collapsing Categories and Polylang

Hi,
thank you for your amazing plugin.
It seems that with polylang, I can’t hide/exclude certain categories.
The exclude basically works fine, when I’m using only 1 widget (I hide the english categories), but when I add another widget and display it only in the english version of the website, I have a weird behaviour.

Sometimes it works, sometimes it doesn’t:
The second widget only displays the second categories, but if I open an article, or change page, the switch doesn’t work anymore. So I end up having some categories that are supposed to be excluded in the second widget that do appear.
I’ve tried everything, but same result everytime.

Polylang works fine with all other tier widgets of my website, (I’m using a couple). looks like the plugin retains the information language “somehow”, but even with the cookie set unchecked, still have the same issue. I ended up to use a classic categorie widget for the EN version and use yours for the french version 🙂
